The DC AFCI is within the inverter. There is one brand/model that I was made aware of recently.
IMHO, if there is nothing readily available, then this cannot be enforced.
All of the solar that I have reviewed, and what is in the 'pile' is all under '08. I expect a lot more solar applications coming into the office before 11/07/12!
edit: Also, a lot more installs going to micro inverters would solve this issue.
